Description

Ascites exudation preventing device

Technical Field

The utility model relates to the technical field of ascites seepage prevention, in particular to an ascites seepage prevention device.

Background

The abdominal cavity drainage is a surgical mode for discharging ascites (pus, blood, lymph fluid and the like) in the abdominal cavity out of the body through a drainage tube.

When a patient performs abdominal drainage, there is a case where ascites does not enter the drainage tube but oozes out from between a puncture hole in the abdomen of the patient and the outer wall of the drainage tube. The exuded ascites can cause local skin to be moist, increase discomfort of patients and increase infection risk; the exuded ascites can pollute clothes, quilt covers and bed sheets, and the cleaning workload is increased.

For this purpose, barrier devices have been developed. For example, in chinese patent application No. CN 202121522465.5, a "barrier device for drainage tube" is disclosed. The device includes the drainage tube, and the surface of drainage tube is equipped with the toper piece, and the conical surface of toper piece is equipped with the shunt outlet, and shunt outlet and drainage tube intercommunication, the top surface of toper piece are equipped with the gasbag, and the top surface of gasbag is equipped with the air cock, and medical adhesive piece has been cup jointed in the surface slip of gasbag.

When the medical adhesive patch is used, the medical adhesive patch is attached to the skin of a patient, air is conveyed to the air bag through the air tap, the air is conveyed until the area of the air bag is increased and covers the area of the puncture hole, then the conveying of the air is stopped, then the ascites is sucked out through the drainage tube, the ascites is prevented from flowing out of the periphery of the drainage tube through the conical block in the process of sucking the ascites, the ascites accumulated on the periphery of the drainage tube can enter the drainage tube through the shunt opening, and the puncture hole is sealed through the air bag and matched with the shunt opening, so that the anti-seepage purpose is achieved.

Because the disease states of different patients are different, the ascites exudation risks are also different. For patients with large abdominal water volume, the abdominal pressure is increased, the ascites is more likely to exude, and the force of the conical block at the extrusion puncture hole is increased at the moment, so that the seepage prevention capability is improved; for patients with smaller ascites, the risk of ascites exudation is reduced, and the extrusion force of the conical block needs to be reduced at the moment, so that the discomfort of the patients is reduced (the greater the extrusion force is, the more the patients feel compression, and the discomfort of the patients is aggravated); in the ascites discharging process, the abdominal pressure of the patient is gradually reduced, and at the moment, the extrusion force of the conical block is required to be reduced, so that the uncomfortable feeling of the patient is reduced.

The existing anti-seepage device can realize anti-seepage effect, but the extrusion force of the conical block is inconvenient to adjust, so that the use flexibility of the anti-seepage device is reduced.
